Epoxy Fiberglass Mesh for Dry-Type Transformers and Reactors
Epoxy Fiberglass Mesh is a high-strength electrical insulation and reinforcement material made from fiberglass mesh impregnated with epoxy resin. It is widely used in cast resin dry-type transformers, reactors, instrument transformers, and other epoxy-cast electrical equipment. The material combines high mechanical strength, excellent electrical insulation, low partial discharge, and good high-temperature resistance.
| Base Material | Fiberglass |
|---|---|
| Resin | Epoxy Resin |
| Thickness | 0.4-2.4 mm |
| Thermal Class | F / H |
The fiberglass reinforcement provides high tensile and mechanical strength, helping improve the structural stability of epoxy-cast insulation systems.
The epoxy resin coating provides reliable electrical insulation and good compatibility with epoxy casting systems.
The resin-impregnated mesh helps reduce air gaps and internal voids, supporting low partial discharge performance in cast-resin insulation systems.
Epoxy Fiberglass Mesh is available in different thermal classes, including F-class (155 °C) and H-class (180°C), for different electrical insulation requirements.
The open mesh structure allows epoxy resin to penetrate the fiberglass reinforcement, creating a strong and stable composite insulation structure.
